Isolating flanges/joints are required in cathodically protected pipeline systems to electrically isolate the pipeline from customer meter stations, pumping stations, points of ownership and other in-line sections. Typically the corrosion engineer plans and selects the areas for the installation of these devices in the piping system during planning and/or pre-construction meetings. However in practice, the actual installation of isolating flanges is left up to the engineering- construction group who may have little knowledge of the requirements to have effective electrical isolation. Field fabricated isolating flanges could be rendered ineffective by over torquing and improper alignment, inadequate coating internally and externally, improper selection of gaskets, sleeves, and washers, etc. This paper will discuss the use of high dielectric resistance materials and the construction of preassembled isolating flanges that includes coating, hydrostatic and electrical testing techniques. This approach eliminates the high costs associated in replacing damaged, leaking, or shorted flanges from the pit falls of improper techniques used during construction.

The monolithic isolation joint is a sealed system, which obscures the individual components inside. How does one perform due diligence on a sealed, discrete system to ensure it will serve well over the asset lifecycle? We will set out a 5 section regimen.
